WALL STRUCTURE Specification of Letters Patent.

Patented July 16, 19Q7.

Application filed January 4,1907. Serial No. 350,760.

To all whom 'it may concern:

Be it known that I, \VILLIAM PINCKNEY FRANCIS, a citizen of the UnitedStates, and a resident of Pensacola, in the county of Escambia and Stateof Florida, have invented a new and Improved Wall Structure, of whichthe following is a full, clear, and exact description.

This invention relates to improvements in wall strue tures for buildingsor the like of a composite character, that is, having inner and outerfacing walls of brick, tiling, or other manufactured hard material, anda filling of concrete, the main object being to provide a simplemeansfor clamping the facing or inner and outer walls from bulging outwhile tamping the concrete filling, thus providing a perfectly smoothwall.

I will describe a wall structure embodying my invention and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is an elevation of a portion of a wall and showing clampingdevices embodying my invention; Fig. 2 is a plan thereof; Fig. 3 is aplan with the clamping devices removed and illustrating tie rods asplaced in position before the elevation of the facing walls iscontinued; Fig. 4 is a vertical section; Fig. 5 is a sectional detailshowing one of the clamping screws employed, and Fig. 6 is a partialplan view, with parts in section, showing a hoop binder which may heemployed.

Referring to the drawings, 1, 2 indicate the inner and outer or facingwalls which are spaced apart and built up-of brick or similar materialwith mortar or other cement. At intervals there are spaced cross walls 3which form pockets 4 for the concrete. Assuming the wall to have beenbuilt up to a short height, tie rods 5 are placed upon the facing wallsand extend across the pockets, these rods 5 having eyes 6 at the outerends, the purpose of which will hereinafter appear. 'Longitudinallydisposed tie rods 7 are placed on the top of the facing walls andinwardly turned hooked ends 8 thereof are projected into the pockets soas to form ties to be embedded in the concrete. I may also employ withinthe pockets a plurality of vertical tie rods 9. The laying of the facingwalls is now proceeded with until the walls reach a predetermined height,when the devices embodying my invention come into play. The holding orclamping device consists of draw bars 10 having hooks 11 at the lowerend for engaging in the eyes 6. The upper ends of the draw bars extendslidably through keepers 12 and are held as adjusted therein by means ofset bolts 13. These keepers are attached to opposite pressure bars 14,be-

ing connected by cross bars 15 which come directly over the walls 3.After placing wooden strips 16 on the upper sides of the facing walls,clamping screws 17 operating in blocks 18 carried by the pressure bars,are to be forced downward upon said wooden strips, the draw bars, ofcourse, engaging closely against the outer surfaces of the facing walls.The parts are to remain in this position until concrete is tamped in thepockets, and when the concrete becomes sulliciently set, the building upof the facing and cross walls is continued to a predetermined height.Before this building, however, it is obvious that the clamping devicesare not in connection with the wall. After building up this secondsection, the clamping devices are to be placed in position and the hooksll engaged with the eyes 6 placed in the wall above the first-namedeyes, and this is to be continued until the wall shall have reached thedesired height. Upon finishing a wall, the eyes (3 are to be cut off,leaving the ends of the rods 5 flush with the outer surfaces of thewalls.

With my invention the use of wooden molds is ohviated, which mustnecessarily be used with walls consisting wholly of concrete or likematerial. The blocks is are adjustable or slidable on ribs 19 formed inthe inner sides of outwardly opening slots 20 on the ends of thepressure bars. Tie loops 21 extend from the walls into the pockets forreceiving the concrete. In Fig. 6 is shown a hoop binder, which may beemployed if deemed necessary or desirable.

It is to be understood that the clamping device may be used on the outerwall alone and be omitted from the inner wall, if found desirable inpractice and according to the exigencies of the situation.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

\ 1. For use during the construction of a building wall having inner andouter facing walls consisting o1.- brick or similar material and havingcross walls forming the side walls of pockets for concrete. a clampingdevice consisting of pressure liars extended along the facing walls, andat the inner and outer sides of the pockets, cross bars con nectingopposite pressure bars and designed to pass over the wall pockets,clamping screws carried by said pressure liars. draw hairs extendeddownward from said pressure bars and engaging with the outer side of thefacing walls. and means for anchoring or securing the lower ends of saiddraw bars.

2. For use in the building of walls consisting of inner and outer facingwalls spaced apart and transverse walls in the space at suitableintervals, a clamping device consisting of pressure burs designed toengage over wooden strips placed on the top of the facing walls.opposite pres sure litllS being connected one with the other. scrcwscarried by said pressure bars for engaging with said wooden strips. eyesarranged in the surface walls, draw bars extended downward from thepressure bars, and hooks on the ends of the draw bars for engaging withsaid eyes.

2!. For use in the construction of a building wall having inner andouter facing Walls spaced apart and tie rods arranged therein, of rodsextended through the opposite facing walls and terminating in eyes atthe outer sides of said facing walls, pressure bars designed for passinglengthwise over the top of the facing walls, clamping screws adjustablealong said pressure bars, cross bars connecting opposite pressure bars,draw bars adjustable vertically with relation to the pressure bars andcarried thereby, and hooks on the lower ends of said last-named bars forengaging-with the eyes.

4. Means for retaining spaced walls in position during the introductionof concrete, comprising; pressure bars for engaging the tops of therespective walls, cross bars con necting the pressure bars, draw barsadjustably connected with the pressure bars and engaging the outer sidesof the 'WflllS, and means for anchoring the lower ends of said drawbars.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
